Review on Resort Chef Non-Slip Safety Mat: Keep Kitchen Cutting Boards Secure, Hygienic, and Dishwasher Safe by Takeshi Krzywicki

They're so thin they warp like crazy and you can't stand them up or put them on the counter. They don't sit flat on the counter and act like a stepping stone, bouncing up and down to cut food. Nothing compares to trying to cut something with a razor sharp knife while it's moving up and down and/or spinning. For a cutting board, you need a flat, firm surface that won't move under your hands. They're also harder to clean because they bend when I rub them in the sink. I don't get any positive feedback on these cutting boards; They are incredibly dangerous to use and very difficult to clean - the worst chopping boards I have ever used. I just can't think of a use for them, so I give my goodwill.
